Researchers analyzed the top queries for health terms -- abdominal pain, headaches, shoulder pain, migraine and hundreds of others -- and tracked how the numbers of searches for those terms changed during the recession, from December 2008 through December 2011, compared with levels before the recession began. The study published in The American Journal of Preventive Medicine February issue reveals that stomach ulcer symptoms rose 228%, with 1.48 million extra queries, and headache symptoms, rose 193%, with 1.52 million extra queries.
